Definitions

  • the present invention relates to an anti-pinch safety device equipping doors or windows with automatic operation, notably equipping public transport vehicles such as buses, trams, metros, etc.
  • the present invention relates to a device for controlling the operation of the door which is simple to implement, which is reliable over time, which allows instant knowledge of the state of the door, position, speed, acceleration and which is not very sensitive to any electrical disturbance in the storage of set values.
  • the invention provides an anti-pinch safety device for an automatically operated door or window, in particular for a public transport vehicle, characterized in that the door is connected to a position sensor which continuously measures and transmits the position of the door to a computer which analyzes the signal transmitted by the sensor to calculate, on the one hand, the instantaneous speed of the door so to determine the direction of movement of the door and, on the other hand, the instantaneous acceleration of the door which is compared to a determined threshold to trigger a control signal, transmitted to a power unit, causing a stop or a reversal the direction of movement of the door.
  • the sensor can be a potentiometer linked to the movement of the door and which continuously transmits the angular position thereof with infinite resolution.
  • This potentiometer is used both to know the state of the door during its opening or closing movements and to know if it is at the end of the opening or closing travel in order to isolate the anti-pinch function.
  • the originality of such a device is that by deriving the position signal for the first time, the speed is obtained and therefore the direction of travel of the door is known and by deriving the position information a second time.
  • the acceleration of the door is obtained, the value of which is compared with a threshold previously stored in memory in order to trigger a control signal causing a reopening if the door was in a closing phase, or a stop if the door was in a phase opening hours.
  • the acceleration threshold from which a control signal is emitted is independent of external disturbances (temperature, aging of the door, etc.) and therefore constitutes a simplification compared to existing systems.
  • the driver by pressing any of these switches, causes the doors to open under the control of the computer via the associated potentiometer. If, during this opening, an obstacle is interposed in the movement of the door, a stop is decided by the computer by controlling the solenoid valve S1, S2 or S3 depending on the door.
  • the computer will control the associated E solenoid valve, which will trigger the actuation of the cylinder in the opposite direction and consequently the closing of the door.
  • This closure is monitored by the computer via the potentiometer. If an obstacle is detected, the door is controlled in the opposite direction towards reopening. As soon as the information from the potentiometer is equal to Xo, the obstacle detection on closing is canceled, the door being completely closed.
  • each leaf is equipped with a position sensor, the signals coming from these two sensors being transmitted to the same computer which analyzes these signals so that the control signal causing a stopping or reversing the direction of movement acts in the same direction on the two leaves of the door.
